SANTA CLARA — Nnamdi Asomugha, a Cal product and formers Raiders cornerback, is coming back to the Bay Area — at least for a free agency visit Thursday to the 49ers, multiple outlets are reporting.

Asomugha was released by the Philadelphia Eagles on Tuesday, only two seasons after signing a five-year, $60 million deal that drew him away from the Raiders.

The 49ers signed their first free agent Wednesday, coming to terms with defensive lineman Glenn Dorsey while also hosting veteran defensive back Charles Woodson, who didn't agree to an immediate deal.

Asomugha, who will turn 32 in July, had four interceptions in his two seasons with the Eagles after earning Pro Bowl honors his final three years with the Raiders, Oakland drafted him in 2003 with the 31st overall pick. (Coincidentally, that's the same draft slot the 49ers hold in the 2013 draft next month.)

Interceptions have never been a big part of Asomugh's game, aside from the career-high eight he produced in 2006 for a Raiders team that went 2-14.

Asomugha is also considering the New Orleans Saints, Houston Texans, Denver Broncos and Arizona Cardinals, according to recent reports. His visit to the 49ers was first reported Wednesday morning by CSN Bay Area.

The top four cornerbacks from the 49ers' Super Bowl run last season remain under contract, including starters Carlos Rogers and Tarell Brown, and top reserves Chris Culliver and Perrish Cox.

The 49ers pursued Asomugha two seasons ago, but they ended up signing Rogers to a one-year deal and Asomugha headed to the Eagles.
